after you configure the main screens for each feature. For example, if you want
to configure a trunk for load-balancing, you should configure the member
interfaces before you configure the trunk. After you configure the trunk, you
should configure a policy route for it as well. (You might also have to configure
criteria for the policy route.)

6.1 Object-based Configuration

The ZyWALL stores information or settings as objects. You use these objects to
configure many of the ZyWALL's features and settings. Once you configure an
object, you can reuse it in configuring other features.
When you change an object's settings, the ZyWALL automatically updates all the
settings or rules that use the object. For example, if you create a schedule object,
you can have firewall, content filter, and other settings use it. If you modify the
schedule, all the firewall, content filter, and other settings that use the schedule
automatically apply the updated schedule.
You can create address objects based on an interface's IP address, subnet, or
gateway. The ZyWALL automatically updates every rule or setting that uses these
objects whenever the interface's IP address settings change. For example, if you
